Application led January G, 1913. Serial No. 740,450.

To all whom it may concern Be it known that I, REINHOLD KRUMMING, acitizen ofthe United States, residing at Milwaukee, Wisconsin, haveinvented certain new and useful Improvements in Temporary Binders orLoose-Sheet Holders, of

which the following is a specification.

This invention relates to improvements in temporary binders or loosesheet holders.

The main objects of this invention are: First, to provide in a temporarybinder, an improved adjusting means. Second, to provide an improvedtemporary binder of the post type which is simple and economical instructure and one which is at the same time very easily manipulated andsatisfactory in use. Third, to provide in a temporary binder, animproved post.

Further objects, and objects relating to structural details willdefinitely appear from the detail description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a.

part of this specification, in which:

Figure I is a detail inside plan of a structure embodying the featuresof my invention, the covers being open or extended. Fig. II is anenlarged detail section taken on a line corresponding to line 2--2 ofFig. I. Fig. III is a perspective view of the cover members 3 and t withthe binding omitted. Fig. IV is a detail section on a linecorresponding'to line 4-4 of Fig. II. Fig. V is a detail section on aline corresponding to the broken line 5-5 of Fig. II. Fig. VI is adetail section on a line corresponding to line 6 6 of Fig. IV. Fig. VIIis an enlarged detail section on a line corresponding to line 7-7 ofFig. I. Fig. VIII is a detail section of the cover members, on a linecorresponding to line'8-8 of Fig. I. Fig. IX is a detail perspective ofone of the post members 8 before the same is attached to the covermember. Fig. X is a perspective view of one of the attaching members 15.

In the drawing similar reference characters refer to similar partsthroughout the several views, and the sectional views are `taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the structure illustrated is provided withcovers 1 and 2 which are provided with binding members `3 and 4respectively. The binding` members are connected to the covers bysuitable flexible hinges 5. The binding or cover members 3 and 4 arepro-vided with inwardly projecting telescoping back members or portions6 and 7 respectively, which form the back of the binder. Each covermember' and its respective back member are preferably formed integral,the same being pieces of sheet metal bent into angular form, as shown.The binding posts are made up of outer members 8 secured to the covermembers 3 and inner members 9 secured to the cover members 1. The innerpost members are adapted to telescope into the outer members, as clearlyillustrated in Fig. II. The post members 8 are preferably provided withweb-like shanks 10 on their rear edges, the shanks being provided withsecuring tongues 11, while the post has downwardly projecting securingtongues 12, on its lower end. The post member 8 and its shank 10 and thetongues on the shank and post are preferably formed integral of a pieceof Vsheet metal folded upon itself as clearly shown inl the drawing.

The cover member 6 is provided with slots 13 in its back portion throughwhich the tongues are arranged and clamped upon the outer side of theback portion. The tongues 12 are arranged through openings 14 in thecover member 3 and clamped over the attaching members 15. The tongues 12are formed by cutting away opposite sides of the post, as shown in Fig.IX. The attaching member 15 is spool-shaped, the tongues being foldedinwardly over the narrow portion thereof as illustrated. This forms avery rigid and secure attaching means for the posts without the use ofsolder or threaded parts. The attaching means is of importance as itwill be readily understood thatvit is a desirable feature to attach theposts on which strain is put in use to the sheet metal cover memberssecurely and at the same time in a manner that leaves no objectionableprojecting parts.

The inner posts are adjustably secured within the outer posts byproviding the clamping or engaging members 16 which are mounted onpivots 17 carried by the inner posts, t-he inner posts b-eing slotted at18 to permit thev engaging or clamping member being swung intoengagement with the walls of the outer post member, as shown in Fig. IV.The engaging or clamping member 16 is actuated by the actuating member19 provided wit-h an actuating screw 20, the member 19 beinglongitudinally slotted at 21 to receive theengaging member, the ends ofthe slots acting on the edges of the engaging member to swing it intoand out of its engaging position, the member being actuated to impingeon or clutch the walls of the outer post member when the actuatingmember 19 is drawn up by its screw and being released when' that memberis forced down, as by the spring 22,-see Figs. II and IV. The head ofthe screw 2O is slotted at 23 to receive a screw driver, key, or thelike. The spring 22 bears against the collar 24 secured to the covermember 1. IVhen the screw is turned to release the actuating member theactuating member is pushed inwardly by the spring 6, throwing the member16 out of engagement. I sometimes provide the screws with suitablefinger pieces instead of slotting them, as illustrated.

The pivot 17 in the structure illustrated is extended at one end toengage the groove 25 formed by the shank 10. This prevents the turningof the inner post member or the attaching member which is slotted at26,- see Fig. II-to receive the pivot.

rIhe center post is not provided with adjusting means, but is providedwith means for extending the binder when the adjusting means isreleased, a spring 27 being arranged in the outer post member 28 toengage the inner post member 29. See Fig. VII.

To assist in supporting the parts in alinement, the back member 7 isprovided with a flange 30 which embraces theedges of the back member 6,as clearly shown. The end of' the tubular actuating member 19 islongitudinally crimped as shown in Fig. VI to reduce its bore, theportion so reduced being internally threaded to receive the adjustingscrew 20.

As previously stated, my improved binder is very simple and economicalin structure, and is at the same time easily and quickly adjusted andvery durable.

I have illustrated and described a preferred form of my improvements.Various modifications will, however, readily suggest themselves to thoseVskilled in the art to which this invention relates; I desire, however,to claim my improvements specifically in the form illustrated as well asbroadly within the scope of the appended claims.

I-Iaving thus described my invention, what I claim is newkand desire tosecure by Letters Patent is:
